We report the case of a woman who presented to the medical emergency room with upper thoracic inlet syndrome six months after being treated for cancer of the left breast with surgery, radiation, and chemotherapy. A port-related occlusion of the superior vena cava was diagnosed on the basis of the history, physical findings, and diagnostic images. ⋯ Implanted port systems facilitate the treatment of the chronically ill by enabling easy and safe venous access. As the number of patients with such systems is growing, there is an increased need for optimized handling and care, awareness of the risks (such as catheter occlusion, thrombosis, and infection), and recognition of complications when they arise.

Deep vein thrombosis is associated with a risk of pulmonary embolism and post thrombotic syndrome (PTS). ⋯ The most important therapeutic measure is prompt and adequate anticoagulation with heparin or fondaparinux. Thrombolysis or thrombectomy is only indicated in highly selected severe cases. The risk of PTS can be reduced by immediate ongoing treatment with compression stockings. Prevention of relapse is achieved using vitamin K antagonists with a target INR of 2.0 to 3.0. The duration of anticoagulation should be tailored to the localisation and etiology of the thrombosis, from at least three months to indefinite treatment. The ongoing risk of bleeding secondary to anticoagulation should be reevaluated at regular intervals as a cost-benefit analysis. New anticoagulants for acute and long term treatment will soon be available for clinical use.
